8 Claims. (01.86-47) 'I'his invention relatesvto a method of packaging aplurality of cartridges into pockets of a cardboard carton suitable forshipment to eld stations or supply houses and the like.

The mechanism provided in this machine singles out cartridges from ahopper and places them oneY by one into individual pockets within acardboard container. Improvements arise inthe handling of saidcartridges and the speed with which they are placed within said boxesfor their quick delivery to the vital areas where needed. The handlingof the cartridges and the delivery of the completely filled cardboardboxes onto the discharge conveyor oi the machine for immediate deliverywhere needed will be clearly deiined in the following description ofythe machine of which;

Re'ferringmore,particularlyto the drawings it will. be` understood that.the machine'will com'- prise a suitable. supporting `frame.- generallyindicated at l. end frames 2 tied together byfa cross piece member 3which houses the vsupporting bearings for the overhangingcartridge-drums on the right side looking in the direction of Fig. 3,and their respectivedrivemechanisms asseen on the left sidein the same.view. -In front of end frames 2 and supporting the boxhopper mechanism 4is a U-shaped frame` member 5 which`4 is also supported by main frame l.

The box hopper mechanism vdelivers empty boxes to the box conveyor to.be filled withvcartridges and finally. pushed Y onto a discharge. beltready tobe packed Vfor shipmentA to the Veld stations or. whereverneeded. The box hopper con-V sists o1 hopper sides and back panel .lsupported by frame' mounted upon supporting frame member 5. Theboxes. tobe lled are of cardboard and contain one longitudinal and nineV` crosspartitions forming two rows of ten cartridgef'receiving pockets. Alongone horizontal edge of said box is hinged a ap portion large enough toretain' the cartridges-in the pocketsi in both rows when said flapisclosed. n

. Theoperatorl places ythe empty boxes llL'just Mounted upon this mainframe, I are described, in the hopper one above the other in a singlepile (Fig. 1) with the flaps II toward the front and top. The lowermostbox will rest on bottom support member I2 with the others on top of it.A pusher I3 reciprocates back and forth to push said boxes into the pathof a reciprocating flapper I4 which pushes them down in front of thelugs on the continuously moving box conveyor i5 to be carried alongthrough the machine.

'Ihe box hopper mechanism is driven from shaft which rotatescontinuously. A crank 2i pinned to shaft 20 oscillates lever 22 mountedon stud shaft 23 by a link connection 24 to said lever. Pusher I3 isslidably mounted in ways 25 on frame member 5. Located between said waysis a slidable platform member 26 which supports member 21 and carriespusher` I3 for oscillation in ways previously mentioned (Fig. l). PusherI3 is oscillated back and forth by yieldably mounted lever 21 connectedby a link 28 to a boss 29 formed on the under side of platform 2t, saidlink 28 being pivotally secured to boss 29 by a pin 33. Lever 21',mounted on stud shaft 23, is yieldably secured to drive lever 22 by aspring 34 which is hooked between pin 35 on lever 22 and pin 36 on lever2'I'. Lever 21 carries an adjusting screw 38 which is constantly forcedagainst stop pad 39 on lever 22 by tension from said spring 34. Thepusher I3 oscillates back and forth pushing one box after another to thebox conveyor. Should anything happen so as to cause a box to jam orbecome lodged in the mechanism for any reason, lever 22 will follow themotion of crank' 2| but lever 2l" and pusher I3 may anism. A cover 49which encloses pusher i3 also acts as a back-stop to hold the boxes I tas the pusher I3 returns from its forward position, as in Fig. 14, sothat said pusher may pull itself out from under the lowermost box. Assoon as the pusher I3 clears the box I0, said box'will fall immediatelyonto the bottom member I2 of the hopper directly in the path of thepusher I3 as it advances on its next forward stroke (Fig. 15). A bracket42 mounted on hopper frame 8 carries side guides 43, one of which isshown in Fig. 1 as in the back. The front one has been removed forclearance. Centrally disposed between said side guides 43 and mountedfor oscillation up and down in a swinging motion from pivot stud shaft44 mounted in bracket 42, is a bell crank lever 45 which carries ailapper plate I4 to contact the box pushed under it by the pusher i3 andslap it down onto and in front of the oncoming lugs of the continuouslymoving box conveyor. The action of the pusher I3 and the ilapper plateI4 is timed in perfect unison with the continuously moving lugs on thebox conveyor so that each box is placed simultaneously between said lugson said box conveyor. The front of the box, as seen traveling in thedirection of the arrows in Fig. 16, contacts the lug pushing thepreceding box and the back of the box is contacted by the lug pushingit, therefore positively guiding each box. The box conveyor is, in turn,in perfect timed relation with the four cartridge transfer drums so asto cause each pocket in each box to be positively aligned with itsrespective pocket in the continuously rotating cartridge transfer drumsso that as the conveyor travels with the boxes and the transfer drumscontinuously rotate and deliver the cartridges, all the pockets in allthe boxes will be filled with cartridges, the method for which will beexplained more fully later in the description.

The apper plate i4 moves continuously to slap one box down onto theconveyor after another. To accomplish this, bell crank 45 is connectedby a link 45 to a lever 4'! pivotally mounted at 48 to frame 5 in backof box hopper 4. Lever 4l carries a roll 49 which is held in contactwith cam 59 by tension of spring 5I. Cam 55 is securely fastened tohopper drive shaft 23 which rotates continuously in the direction of thearrow (Fig. 1). As the box is pushed under the apper when said flapperis in its upraised position indicated by dotted lines (Fig. 11i) it willbe held momentarily between side guides 43, supported from frame 42(Fig. 1), until plate I4 contacts the top of said box and pushes it downtoward the box conveyor traveling along underneath. The box will beguided further by radially shaped guides 53 and 54 respectively. Theflap II will strike against the rounded portion 55 of hopper bottommember I2, which also comprises guide portion 53, and cause said flap tobe bent upwardly as the box is pushed down onto the box conveyor as seenin Fig. 15. With the flap raised in this position, access to the severalpockets in the box will be unobstructed when the cartridges are fed fromthe transfer drums into said pockets. The iiaps are retained in thisuplifted position during the boxes travel through the machine by a guidemember 55 (Fig. 16). Said flap guide 5E will be cut away, at the fourcartridge supplying stations (Fig. 4) enough to allow the entrance ofthe cartridges into said pockets in said boxes and for the free actionof the rotating pusher which will be described later.

' The box conveyor carries empty boxes from the box hopper, along pastthe four cartridge loading stations where the boxes are filledsimultaneously with cartridges and finally delivers them onto thedischarge conveyor which will be explained later. The box conveyor ismade up of box-carrying lugs 58 interconnected by links 59 to form acontinuous conveyor chain I5 (Fig. 16). Box carrying lugs 58 haveextensions 6E) on each side which ride in ways 6I formed in supportbracket 62 mounted on frame i. Box retaining and pushing lugs 53 areformed out of lugs 58 and are centrally disposed between the boxconveyor bottom plates 64 secured to the top of bracket 62 and spacedapart as seen in Fig. l so as to receive box retaining and pushing lugs63 as they move continuously with the boxes through the machine. Sideguide 54 associates with guide 53 to form a channel at the box hopperstation by which the boxes will be guided transversely as they arecarried along on the conveyor chain.

Box conveyor chain I5 travels over an idler sprocket 58 supported bybracket 69 which in turn is mounted on frame I (Fig. 1). A guard 1Bencloses sprocket 68 and conveyor chain 'I5 as the conveyor supportbracket 62 does also along the entire length of the machine. At the`discharge end of the machine (Fig. 13) is located the conveyor chaindrive sprocket II which is pinned to conveyor drive shaft 'I2 forcontinuous operation.

Box guided at the boxhopperstation isreplaced by guide 65 (Fig. 3) whichlgives support to the lower corner of the boxes aftersaid boxes leavesaid -box hopper station and are placed securely between the conveyorlugs 63 on the box conveyor to be filled with cartridges and deliveredonto the discharge conveyor, which will be described later. Box flapguide v5 (Fig. 3) replaces guide 53 (Fig. l) at the box hopper station,to form a continuous channel when associated with bottom plates B4 andlower box corner guide `|55 secured to plate S4 throughwhich said boxesare pushed. Several brackets are mounted successively along the lengthof conveyor support bracket B2, one of which is shown in Fig. 3 as at15. Through these several brackets l5 passes a shaft jwhich carries, atdifferent intervals, brackets 11one of which is also shown-securelymounted upon shaft 'i6 to be readily pivoted with said shaft by themovement of handle '.'Salso secured to shaft T6 for the inspection ofboxes as they travel along on the conveyor l5. Secured to bracket 'Vi isa box corner guide member 'i9 in the form of an angle iron. Alsoysecured to bracket 11 is a box hold-down and flap guide member combinedas shown at Bil. When bracket l? is in its proper position as in Fig. 3box holddown member 8i! and flap guide member 56 will together form achannel as seen in Fig. 3 for boxflap to be positively guided in itsbentup position during its travel through the machine so the cartridgemay be easily placed within the several pockets in said boxes.

For delivering cartridges to the cardboard boxes this machine has fourcartridge chutes, the construction of which is similar to machines builtbefore and will not be described in detail. The several chutes are lledby any suitable automatic means so as to deliver a constant flow ofcartridges to the receiving drums for their transfer into the transferdrums and hence into the several pockets of the cardboard boxes forshipment. Detecting mechanisms may be employed in the several chutes forthe automatic stopping of the machine, should a gap occur in thecartridge supply in anyone chute. `Cartridge guides 85 which make upsaid chutes are disposed vertically above the center of cartridgereceiving drums (Fig. 16).

For delivery of the cartridges from the chutes r 85 the machine consistsof four cartridge receiving drums mounted centrally and vertically abovefour cartridge transfer drums (Fig. 16). The semi-circular pockets insaid transfer drums coordinate with the pockets in the cardboard boxesbeing carried along on the box conveyor as both move continuously whilethe cartridges are being delivered from the former to the latter. Themethod of delivering said cartridges from one to the other will bedescribed later.

The uninterrupted flow of cartridges fall by their own weight throughsaid chutes 85 into the several semi-circular elongated pockets whichare disposed radially around the periphery of the receiving drums 96,9i, 92 and 93 respectively, said drums being mounted for continuousrotation on shafts Sli, 95, S6 and 91 respectively (Fig. 16). Saidshafts are journaled in bearings in cross member 3 and carry on theiropposite ends gears S3, 99, |69 and lili respectively (Figs. 2 and 3).Secured to said spur gears 98, 99, iliil and lill are respective bevelgears |62, IBJM and |95 which are continuously driven by bevel gears 66,|51, |68 andl severallymounted on continuously.V rotating driveshaft .ilEl, which is-:journatled 7 6 in bearings mounted on upright .framelmembers 22 supportedffrom base I, previously, de-

scribed.

Cartridge transfer drums H2, H3, H4 Vand.

I I5 also contain semi-circular shaped pockets disposed radially aroundtheir peripheries for the purpose of receivingthe several cartridgesfrom the previously mentioned receiving drums. and arecentrally mountedbelow said cartridge receiving drums and are severally supported, onshafts H6, I|'|, ||8 and H9, also journaled in cross member 3 (Fig. 3).Spur gears |29, |2|, |22, and` |23, pinned to shafts IIE, I|'|, H3, and|I9 respectively are driven constantly by spur gears 98, 99, |09, andpreviouslymentioned as driving the four receiving drums.

Therefore thecartridge receiving and transfer drums are driven in a 2.to 1 ratio from drive shaft H9 through said beveled gears mentionedpreviously, saidtransfer drums being constantly rotated in a speed equalto that of the box conveyor for the transfer of cartridges from theradially disposed pockets on the periphery of the transfer drums intothe several pockets of the cardboardA packing boxes held rmly betweenthe lugs on the box conveyor and iinally delivered onto the dischargeconveyor with said cartridges in the several pockets withinsaidcardboard boxes which will be more fully explained later.

The cartridges fall from their respective 'chutes 35 `into the severalpockets |25 in the receiving drums 90, 9|, 92, and 93 respectively. Theyare guided from lateralv movement while in these s everal pockets byS-shaped guides |26 at their base ends' which are towards cross member3, and removable guides |526Y at their tip ends. Guides |26 also.possess a circumferential guiding portion as at, |21 (Fig. 16) to retainthe cartridges in their Yrespective pockets |25 until said pocketscommunicate with Correspondingpockets |28`in the periphery of thetransfer drums disposed directly. below.

' The cartridges in certain pockets in the receiving drums, said pocketsbeingdesignated by numbers l'tolO (Fig. 16) will always fall intocorrespondingly numbered pockets in the transfer drums., The transferdrums will have two sets of said numbers 1 to 10 (Fig. '16) because oftheir half speed as compared to the speed of the receiving drums.vNamely, as the cartridge in pocket number 7 in receiving drum 9|) ridesoff the circumferential guide portion 21 of tip-end guide memberlZe(Fig. 16) 'it will fall into correspondingnuinber 'l' pocket in transferdrum I l2, directly below, as theyboth rotate continuously in thedirection of the arrows.

Looking at transfer drum I2' for example, numbers 1, 2, 3, 4, 5, 6, and7 respectively represent' cartridges in these aforesaid numberedpocketsasr having been transferred into these several pockets fromcorrespondingly'nurnbered pockets l, 2, 3, 4, 5, 6, and 7 in receivingdrum 96, cartridge number 7 being vthe last one to have been transferredinto drum ||2 according to the position here shown. Cartridges numbered8, 9 and 10 are Vretained in their several pockets in drum 9i) 'but'will'eventually fall into correspondingly numbered pockets 8, 9 and 10in transfer drum H2. Therefore, pockets numbered 6, 5, 4, 3 and 2 inreceiving drum 90 are now empty and the severa-l cartridges that were inthese pockets lhave been transferred'into pockets 6, 5, 4, 3, 2 and alsonumber r1 in transfer drum H2. Pocket number lin receiving drum nowhasanother cartridgein; it :whichzitzhasfjust` Y received 'from thesupply chute 85. As the drum 9|) turns continuously, the followingpockets 2, 3, 4, 5, etc., around the periphery of the drum will also befilled again and as they travel down the other side of thecircumferential arc in the direction of the arrow they will be guidedand held into their respective pockets until they ride off thecircumferential guiding surface |21 into their correspondingly numberedpockets in the receiving drums.

Pockets |25 in all the receiving drums are rounded on their leadingedges according to the direction of the arrow as at |30 so that moretime will be gained for the entrance of the cartridges into said pockets|25 from the cartridge guides 85 while the receiving drums rotatecontinuously. Pockets |25 in all the receiving drums are noticeablydeeper than pockets |28 in the transfer drums. Said pockets |28 arepurposely made shallow so as to enable the cartridge pushers to contactthe lower edges of the base ends of the cartridges and push them out ofsaid pockets |28 in the transfer drums into corresponding pockets in thecardboard packing boxes carried on the box conveyor, which will be morefully explained later in the description. It will be noticed that twoblank spaces numbered 11 occur on the periphery of drum ||2 and one isalso present on drum 90. After a cartridge has fallen into pocket 10 inreceiving drum 90 for example, the cartridge immediately following inthe delivery chute 85 (first unit, Fig, 16) will have ridden onto theblank, arcuated surface of said drum 90 and thence into pocket numbered1 here shown on the drawings in this particular position of the machine.Blank arcuated surface on receiving drum 90 will always register withthe two correspondingly arcuated surfacesalso numbered 11 on saidtransfer drum ||2 as both drums rotate continuously.

Said cartridge handling mechanism just described Will be recognized onthe drawings as the iirst typical unit in a series of four as shown inFig. 16. The other three units operate correspondingly and all are sotimed to each other that each pocket in said receiving drums willcommunicate with the same corresponding pocket in the transfer drumsduring every cycle of their operation and said pockets in each transferdrum have a specific pocket to communicate with in the cardboard packingboxes for the accurate delivery of the cartridges from the transferdrums into said pockets in the packing boxes with the aid of a singlecartridge pusher and also a rotary pusher for each unit, the action ofwhich will now be explained.

Looking at the partial plan view of the cartridge pushing units, Fig, 4,it will be noted that there are four such units each comprising acartridge pusher and a rotary pusher operating simultaneously. Thecartridge pusher pushes the cartridges out of the pockets in thetransfer drum into the several pockets in the cardboard packing boxes afar as its construction will permit. Said cartridges are further pushedhome to their proper position, entirely within said pockets in saidcardboard boxes, by a rotary pusher acting in conjunction with saidcartridge pusher and both operate continuously to deposit saidcartridges into the several pockets in the packing boxes as said boxesare carried along on the box conveyor. Each pocket in each cardboard boxwill contain a cartridge when said box leaves the last transferring unitduring its travel with the box conveyor and will then be delivered,fully packed, onto the discharge conveyor of the machine.

The cartridge pushing unit comprises two .parallel mounted endlesschains |35 each being carried upon three sprockets (Figs. 5 and 6), oneof which is a double driving sprocket |36 mounted on and driven fromshaft |31. Said shaft |31 is continuously rotated by bevel gear |33which meshes with continuously rotating bevel gear |38 suitably securedto constantly rotating shaft |13 (Fig. 2). Said sprockets and drivingshaft |31 are mounted in suitable bearings between the two sides of anH-shaped bracket |60. Said bracket |40 comprises an extension from eachside frame, said extensions being secured by bolts |52 to the under sideof main frame through aperture |43 in said main frame as best shown inFigs. 4, 5, 6, and 8 respectively. Mounted across said parallel chains|35 are cross pieces |45 suitably secured so as to carrycartridgelpushers |45, centrally mounted upon said cross pieces |45 soas to travel between top enclosure pieces |131 mounted along the top ofbracket |150 and spaced apart as at |58 to allow the passage of saidcartridge pushers |415. Multiple cartridge pushers |135, only two ofwhich are shown for clearness, are carried on said parallel chains |35spaced apart from each other along said chains at proper intervals toContact the lowermost edges of the base ends of the cartridges (Fig. 8)as they are brought one after the other into the path of saidapproaching pushers |40 by the continuous rotation of transfer drums H2,H3, H4, and I5 in the direction of the arrows previously described, andthe continuous advancing of said cartridge pushers |56 on chains |35 asthey travel around their triangular shaped course as shown best in Fig.6. Top enclosure pieces |41 mounted on upright sides of bracket |40 areboth made more rigid and the cartridge pusher mechanism is furtherenclosed by front end plate |48 secured to H-shaped bracket side membersat their front ends by bolts |59. The chains |35 supporting saidcartridge pushers |46 ride up onto chain supporting shoes |50 which lieunder the chain rollers so as to give rigid support to said pushers asthey contact cartridges in the pocket |28 of the several transfer drumsand push said cartridges into the pockets of the cardboard packingboxes. f

A slot S may be provided in bracket |50 to receive the squared end of anadjustable member T upon which is mounted one set of sprockets overwhich cartridge pusher chains |35 pass. At the center of a U-shapedextension of member T is provided a bolt and lock nut arrangement whichbears against end plate |58. Chains |35 may be tightened or loosened b-ysaid bolt and lock nut so as to keep cartridge pushers |45 in properalignment and for easy assembly of said cartridge pushers and theirchains respectively. Each of the four cartridge pusher units shown inFig. 4 may be provided with this adjustable feature here shown in Fig.'1 as a modified form.

The cartridge pushers are all traveling transversely to the direction oftravel of the cardboard packing boxes on conveyor I5 as seen best inFig. 4. The entire cartridge pushing unit is mounted in an aperture inthe main frame at an angle sufficient to cause pushers |46 to pushcartridges progressively from the pockets |28 of the transfer drums assaid drums rotate continuously. The location of transfer drum ||2 inrelation to said cartridge pusher, rotary pusher, box nap guide 56, andcardboard box conveyor |5, is best. shown in Fig. 4 indot-dash lines Vonthe drawings. Although the cartridge pushers |46 travel transversal tothe direction of travel of the box conveyor |5 said pushers areconstructed so that the pushing surface |55 of each pusher is parallelat all times to the direction of travel of said box conveyor l5 andtherefore said pushing surface will push flat against the base ends ofthe cartridges (Figs. 4, 8, and 9) as it contacts them to push them fromtheir pockets |28 in the transfer drums into the several pockets in thecardboard packing boxes traveling along on the box conveyor I5.

Referring to Fig. l0, we have a full scale view (Figs. 4, 5, 6, 8) withcertain parts broken away to showhow the several parts are assembled soas to guide the cartridges from their several pockets in the transferdrum ||2 to their corresponding pockets in the cardboard packing box. Inthis view We are looking at the inside front face of the transfer drumjust inside the S-shaped cartridge guide |25. 1t is a View showing theoperation at the rst cartridge transfer unit in Fig. 16 but looking inthe opposite direction from said Fig.

16 with the packing boxes traveling along in the background.

Circumferential guides |51 and |56 (Figs. 4 and .confine the cartridgesto their pockets |28 during their travel, in the direction of the arrowin Fig. 16, from the receiving drum pockets to the several pockets inthe cardboard packing boxes. The lower portions of S-shaped guides serveto guide the cartridges at their base ends from lateral travel towardthe supporting cross member 3 of the machine (Fig. 3). Circumferentialguide |51 is provided with a beveled surface |59 for guiding thecartridges against a lateral movement toward the box conveyor andpacking boxes. The shoulder |59 of the cartridges guides against thisbeveled surface |59 while said cartridges are positioned in the pockets|28 of the transfer drums and are lowered in their arcuated travel ontothe milled-out circumferential surface |69 on lower cartridge guide |6|(Figs. 3, 4 and 10) secured to-the'top surface of aforesaid enclosurepieces |41l (Fig. 4).

Here, said cartridges lie Vfree from guides |51 and-|58fortheir traversejourney intothe pockets of the cardboard packing boxes (Figs. 8 and 10).nally by their contact with the lower edges of the pockets |26 in thetransfer drum. Said transfer drum is continually rotating and by saidcontact with said lower edges of saidpockets |28, carry .said cartridgesalong in the direction of and par- ,allel to, the box conveyor whilethe'cartridge pusher travels in a traverse direction toward said boxconveyor and the face of said cartridge pusher contacts vthe base end ofsaid cartridge and Ipushes italong outof vsaid transfer drumrpocket12s-into .corresponding pockets or cells in the lowermost. row ofthecardboard packing-box on conveyor f;i5. Because of the cartridge pushersbeing mounted on a continuously moving endless chain i'they are not ableto push said cartridges home into the pockets of the cardboard lpackingboxes but leave said cartridges in a posi- (conveyor, ithey` areseverally `contacted simultaneously by a, rotary pusher i operating oon-Said cartridges are still guided longituditinuously in acircumferentialu motion, the path of which is indicated by dot-dashlines |66 in Fig. 9, to contactsaid cartridge base ends and .push themcircumferentially traversal to their longitudinal direction of travel,thereby forcing them home simultaneously into their respective pocketsin the cardboard packing. box. Aforesaid box flap guide 56 isv shown cutaway to allow 'the aforesaid action of the cartridge pushers and saidrotary pushers and will now keepthe properly positioned cartridges C2within their respecpockets. Rotary` pushers |65 are so constructed y(Fig. 11) to contact upper :and lower rows of careach transferunit asthe `box conveyor carries them along andpast the opening in said box`flap guide58. Y

The continuous motion of said-rotary pusher is circumferential inthedirection of the arrow Fig. 9. To accomplish this. said rotary pusher ismounted on two cranks, one of which is driven.

Mounted for rotation infront bearing |16, suitably secured-to main frameI,v is a shaft |1| continuously driven by bevel gears l |12 from driveshaft |13, the continuous drive for'whichwill be explained later. Pinnedto the :top 'of shaft 11| is a rotary pushercrank'member |13 whichcomprises crank pin |14 and crank link pin |15 of crank link member |11.

positioned radially from said pin |14 to form a supplemental crankportion |16 for the operation Mounted on crank pin |14 is the extremeend of rotary pusher arm |18. Rotary pusher arm |18 also comprises anadditional bearing mounted on corresponding crank pin` |14"carried on anidlerrotary pusher crank unit mounted in rear bearing |80 also on mainframe Said idler rotary pusher crank unit mounted in bearing |86 isidentical to driven crank unit mounted in front bearing |10. Therefore,as driven shaft-HI rotates-in a counterclockwise drection,-rotary pusher|65 will rotate in a circumferential path as shown at |66, Fig. 9, dueto the 4construction of doubleoranks |13 and |13 mounted inK aforesaidbearings |19 and |89 respectively, as just described.

It will be noted that the packing box consists of two rows of pocketsseparated longitudinally by' a transverse partition-centrally supportedby multiple vertical partitions spaced apart to form said pockets orcells `within said box. This machine is designed to first llthe lowerrow ofsaid box with cartridges and then the upper row in :the samemanner, .as will .be seen in Figs. 8, 10,

and 16, and will now bedescribed.

As aforesaid, the cartridges fall .from the chutes into pockets |25 inthe receiving drums and are transferred from saidV pockets intocorrespending pockets |28 in the transfer drums. Looking atFig. 16,packing box .Blnow contains cartridges in the lower row designated bynumbers 1,'2, 3, 4, and 5 respectively, said cartridges having beentransferred from pockets |23 in transfer drum ||2 correspondinglynumbered '1, 2, 3, 4, and 5 1espectively,when--said; pocketswere inalignment with leach .otherijust as pockets-|26 numbered 6 and 7 nowlare in this particular aligned position, a full scale view of which isshown in Fig. 10 for illustrating more clearly the Vpossibility of saidpockets |28 yin said transfer drum being in perfect alignment during ashort interval within the cycle of operation of the machine.

'The cartridge pusher contacts the base end of the cartridge when saiddrum and box pockets are aligned as shown by number 7 cartridge in Fig.10 and while the drum continues to rotate, in the direction of thearrow, the cartridge pusher |46 pushes said number 7 cartridge out ofits pocket |28 into corresponding pocket number 7 in the cardboard boxcontainer shown going along in back on conveyor l5, not shown in thisview but previously explained. Cartridge drum ||2 will travel from theposition shown by number 7 cartridge (Fig. 10) to number 6 cartridgeposition which is approximately one inch, during which time saidcartridge pusher will have pushed said cartridge number '7 approximatelythree inches on a traversal path through the transfer drum pocket |28containing said number 7 cartridge. The same operation occurssimultaneously for each cartridge in each pocket of the transfer drums,said operation to be followed up immediately by the aforesaid action ofthe rotary pusher to place said cartridges home fully Within the packingbox pockets.

It should be noted in Figs. 16 and 10 that each drum provides cartridgesfor filling alternate pockets successively in said cardboard packingboxes. By the cooperation and accurate timing of the following drum,which also fills alternate pockets left empty by the first-named drum,the lowermost row of pockets in the packing box will first be completelyfilled with cartridges, the near completion of which is here shown inbox B2, Fig. 16. Namely, cartridge transfer drums H2 and H3 supplycartridges to be placed in the lowermost row of pockets in the cardboardpacking boxes while immediately afterward, drums H4 yand ||5simultaneously provide cartridges for` lling the uppermost row ofpockets in the same aforesaid cardboard packing boxes for their deliveryonto the discharge conveyor, to be explained later.

Referring to Fig. 16, numbers 6, 7, 8, 9, and in box B3 represent wherecartridges with corresponding numbers 8, 9, and l0 now being retained inpockets |28 of transfer drum H2 by circumferential guides |51 :and |58respectively and by S-shaped guide are going to be placed. Number 6cartridge is already as far into its box pocket as pusher |46 can pushit, and the following pusher |46 on cartridge pusher chains |35previously explained is now acting on cartridge number 7 to push itwithin its pocket in box B3 during the time said cartridgevand pocketsare traveling to the position shown by number 6 cartridge.

Referring to the first cartridge transfer unit, namely receiving drum 90and transfer drum H2, it will be noticed on the drawings. Fig. 16, thatif said transfer drum H2 skips the first lower row pocket designated byX in cardboard packing box B1, the very first pocket designated by Ywill be filled in the following box B3. Because of the box alignmentwith said transfer drum in this particular position shown, the lastpocket will be filled with cartridge numbered 5 in the lowermost row ofbox B1 and due to the regular spacing of pockets |28 around theperiphery of drum H2, cartridge numbered 6`in said transfer drum willenter said first pocket Y in the lowermost row in box B3. The boxconveyor pushing chain lug 63 cooperates with the peripheral spacebetween said pockets |28 carrying cartridges numbered 5 and 6respectively and said lowermost row of pockets are alternately lled aspreviously described Following along in this same manner,

cartridge numbered l0 will be placed in the next to the last pocket inthe lower row of box B3. 5 Therefore, peripheral blank space numbered 1lon transfer drum H2 will cooperate with vacant pocket Z in box B3 andconveyor chain lug 63 and the first corresponding pocket in the lowerrow ofthe box immediately following which can be referred tocorresponding pocket X in box B1 here shown so as to cause alternatelower row pockets to be filled in said following box in the same orderas the pockets in box B1 were filled previous to filling box B3 pockets.

A complete cycle of box pocket filling has now been described for thelower row of pockets in the cardboard packing box and the same identicalconstruction and operation occurs for filling the uppermost row in thesame packing boxes with cartridges except that to enable the radialpockets |28 on transfer drums H4 and H5 to cooperate with said upper rowof pockets in the cardboard packing boxes, supporting drive shafts H8and H9 for said transfer drums H4 and H5 respectively are positionedhigher in alignment than aforesaid driving shafts H6 and H1 for saidtransfer drums H2 and I3 (Figs. 2 and 16).

By referring to the third cartridge transfer unit, namely thatconsisting of receiving drum 92 and transfer drum H4 operating to fillthe uppermost row of pockets in said cardboard packing boxes, theoccurrence and operation of peripheral blank surface numbered H on saidtransfer drums is clearly shown as previously described. Alternatepockets numbered 1, 2, 3,

4 and 5 respectively in the uppermost row of box B4 will be filled fromtransfer drum I4 and the remaining empty pockets left by Said drum H4will be supplied with cartridges from correspondingly numbered pockets6, 7, 8, 9, and l() respectively from said transfer drum H5 which actsin conjunction with said drum 4 to lill said upper rows in saidcardboard packing boxes with cartridges, previously described.

To sum up the aforesaid operations required to lill all availablepockets in each cardboard packing box with cartridges as said boxtravels continuously on box conveyor l5 past; four continuouslyoperating simultaneous cartridge transfer units, the action taken is asfollows. First transfer drum H2 will furnish cartridges to ll alternatepockets 1, 2, 3, 4, and 5 respectively as shown placed in box B1 andalternate pockets 6, 7, 8, 9, and 10 respectively as shown being filledin box B3 (Fig. 16). The next box immediately following B3, not shown,will have pockets filled in the order similar to box B1. Thereforecartridge transfer drum ||3 will furnish necessary cartridges to fillempty pockets left in the lowermost row in boxes B1 and B3 respectively,first filling in pockets numbered 6, 7, 8,'9, and 10 respectively asshown after having been lled accordingly in box B4, and 1, 2, 3, 4, and5 respectively in lower row of B2 as here shown in the act of completelyfilling said vacant pockets in said lower row of said box B2. The sameprocedure takes place in filling the upper row of pockets in the sameboxes. Box B5 shows cartridges 6, '7, 8, 9, and 10 respectively in theuppermost row placed within their correspondingly alternate pockets,said cartridges being furnished by transfer drum H4, while box B4 isshown about to receive cartridges numbered 1, 2, 3, 4, and 5 incorrespondingly numbered pockets 1, 2, 3, 4, and 5 respectively. Box B2,immediately following box B4 will have essorage VV'said pockets in theuppermost row filled according to the same arrangement as box B did,namely pockets numbered 6, 7, 8, 9, and v respectively. Cartridgetransfer drum H5 is so 'constructed and timed with relat1on to drum I I4vtransfer drum I I5 will bridge across pockets numbered 5 in the upperrow in box B6 and corresponding pocket numbered 6 in the upper row inbox B5 previously lled by drum H4 and previously described, so thatcartridges numbered 1, 2, 3,*4, and 5 now being retained in drum H5 byguides |51 and |58 respectively will be deposited in the upper row ofbox B5 directly above correspondingly numbered cartridges l, 2, 3, 4, 5respectively, already in place in the lower row of said box. Box BPlshows all twenty cartridges being represented by their respectivenumbers placed in proper order to completely ll said cardboard packingbox fordelivery onto the discharge conveyor.

The bottom-portion of said cardboard boxes has been removed inFig. 16 toshow the available cartridge pockets and the transverse longitudinalpartition separating each longitudinal row of ten cartridges, one abovethe other. Box

`flaps H are also shown in theirV raised position during their entiretravel past cartridgereceiving drums H2, H3, H4, and H5 respectively aspreviously described, and held in this aforesaid raised position bymember 8i) cooperating with iiap guide member 5S (Fig. 3) to form aretaining channel `for said box flaps to travel through, also describedpreviously- During the process of filling the uppermost row ofthecardboard packing boxes with cartridges,

it is very important to guide the cartridges'with `greater care andaccuracy than was required for filling the lowermost row. The object isto .carry the center of the tip-end of the cartridge well above thetransverse longitudinal partition where there are already presentcartridges iillingv all pockets which have been placed there previous tofilling said upper row. To accomplish this, lower guide member ISE?,Fig. 8, is purposely milled deeper on its forward surface |85 andygradually rises to form an inclined surface'l upon which all upper rowcartridges are released vfrom transfer drums H4 and H5 respectively,

surface |85 and also slightly Yabove thelevel `of said transverselongitudinal partition within said cardboard box, serves to level oisaid cartridges high above said transverse partition safely within saidupper row of pockets in said vpacking boxes as said cartridges arepushed simultaneously into said boxes by cartridge pushers |56previously 4 described and shown in Fig. 8. n

Upon'completion oflling all of said pocketsin Yeach cardboard packingbox as said box-is moved Yalong kon conveyor llrsaid conveyor carriessaid y lcompletely filled packing lbox to the #discharge mechanism for.thepurp'ose of vrighting .sai'dfbox and delivering it 'out 4`of ithemachine for `further packing into containers which are finallysent toeld stations Aor ammunition `supply houses or wherever desired. It willbe noticed by the drawings that all of said packing boxes have beenlaying on their sides with the box flaps II held in an upraised positionfor the easy entrance of all of the cartridges into the several pocketswithin said boxes, during their entire continuous travel with the boxconveyor I5 from the time they were severally placed upon said conveyorfrom out of the previously mentioned box hopper station, starting thebeginning of their continuous travel through said machine, to Where theyare now approaching, namely the discharge station. It is the purpose ofthe discharge mechanism to remove said completely lled cardboard boxes,containing twenty cartridges, from the continuously moving box conveyorI5 and place said boxes in an upright position onto a discharge conveyorfor their safe delivery out of said machine.

To accomplish this aforesaid purpose of said discharge mechanism, it isnecessary for the pushing surface of the discharge paddles ISil to movecontinuously in a plane parallel to the continuously moving box conveyorI5. Said dis charge mechanism is supported from bracket 555 mounted onmain frame I (Fig. 13). Rigidly secured to bracket |95 is stationarygear |96 around which three sets ofplanetary gears are carried forrotation on stub shafts |91 and |98 respectively. Said stub shafts areseverally mounted in bearings on disk member |99 which in turn is pinnedat Zii to continuously rotating vertical discharge paddle drive shaft23| supported in bearings 2(22 on support bracket |95 simultaneouslydriven by bevel gear 203 pinned to the lower end of said shaft 23|. Saidbevel gear Zii is driven by bevel gear 204 which is suitably secured toaforesaid box conveyor drive sprocket 7| pinned to aforesaidcontinuously rotating box conveyor drive shaft 'i2 for continuousoperation of the discharge paddles |99. As the planetary gears 2&5travel around the periphery of stationary gear it, with the teeth ofsaid gears in mesh, stub shafts |91 with gears 2i5 rotate inacounter-clockvise direction. Said gears 295 mesh with larger gearsZilli supported on stub shafts ist also jcurnaled in bearings on diskmember iiand cause said gears 255 to travel Vin' a Clockwise directionjust fast enough in vaccordance with' the speed oi rotation ofshait 29|to cause discharge paddles lili), which Vare made part of said gears296, to move continuously in aparaliel path equal to the-direction oftravel of the conveyor.

By this parallel 'movement `of the discharge paddles i3d, said paddlesare brought flatly against the upper portion of the open top of the cardpacking box, eruitaiding twenty carges, it lies on its side between thebox conveyor lugs which have conveyed it from the afcreme tioned boxhopper station to said gc station. Because of the fact that stub s |538mounted on disk member i559, l rotates continuously in a counter-clock.-directi said shafts travel in a circumferential path around drive shaftBecause of the planetary gearing used to drive discharge paddles ltd,previously described, said paddles travel in a oircumferentiallyparallel path to the v,box vconveyort ereiore squarely forcing saidcartridg'e filled cardboard box out from between the conveyor lugs 63 ofbox conveyor I5, over the rounded portion El@ of previously describedconveyor support bracket 62, which runs the entire length of themachine.

The cartridge lled box will rst be eased onto the discharge belt 2 i2 ina leaning position as shown in Fig. 13 in full lines, and as saiddischarge belt travels in the direction of the arrow in 12, thecartridge lled cardboard box Will be cammed into an upright position asshown by dotted lines in Fig. 13 by the diminishing width between theconveyor side guides as shown at 2! l of surface 2H), as the box iscarried along out of the machine on said discharge belt 2 I 2. A boxguide 2515 is provided opposite the line of action during the actualpushing of said cartridge filled box out from between the box conveyorlugs 63 and onto the discharge belt 2 I2 as previously explained so asto conne said box to said discharge conveyor. Said discharge belt 2i2slides over member' 2I3 which in turn supports the weight of the filledcartridge boxes and said belt is driven from flanged pulley 2M. Saidpulley 2M mounted on a shaft in bearings supported from frame I in turnsupports a sprocket 2 I5 which is driven by a chain 24S from a sprocketon a continuously rotating discharge belt drive shaft 2 i?.

To continuously rotate the numerous drive shafts previously mentionedthroughout the description of this machine a motor 223 is provided (Fig.l). A drive pulley 22! secured to said motor drive shaft 222,continuously drives pulley 223 mounted upon a shaft 224 journaled inbearings 22E@ treme end of main frame I as viewed in the direction ofFig. 1. Secured to said shaft 224 is a gear 226 which drives gear 221supported for continuous rotation upon shaft 228 also supported inbearings 229 at the end of frame I. Mounted in bearings projecting frommain frame I, Figs. 1 and 2, is shaft H3 continuously driven by gear I'Mwhich meshes with gear 221, previously mentioned. Therefore, rotarypushers |55 are continuously driven through bevel gears IIZ previouslydescribed as mounted on shaft I'l3 for continuous operation.

Also suitably secured to shaft 228 at the furthermost end of main frameI is a sprocket 230 which drives shaft Hit by a ch'ain I II and sprocketH2 suitably secured to said shaft I l0, thereby providing continuousrotation for all cartridge drums as previously explained. On the extremeend of shaft III), opposite to sprocket H2, Fig. 2, is secured anothersprocket 233 by which .box hopper drive shaft 20 is continuously driven.Shaft 20 is coupled by gearing 235 to stub shaft 235 mounted within boxhopper support frame 5, said shaft 23|.= being continuously rotated by achain 23'! driven from sprocket 233. Said chain 231 drives sprocket 238suitably secured to said stub shaft 236, thereby providing continuousdriving means for the previously described box hopper mechanism. Mountedupon continuously rotating shaft 228 is a worm gear 24d which drivesWorm wheel 24| which is secured to box conveyor drive shaft l2 therebyproviding continuous drive to said shaft l2 for the continuous movementof box conveyor I as previously described. Each cartridge pusher unitpossesses a bevel driving gear I38 previously described as being mountedfor driving shaft I3? to cause said cartridge pushers |46 to travelcontinuously. Said gears |38 of each cartridge which are suitablysecured at the expusher unit mesh with corresponding bevel gears E3Bwhich are pinned to shaft I'l3 for the continuous operation of allcartridge pusher units.
